Traction endurance biomechanical study of metallic suture anchors at different insertion angles

A biomechanical analysis of anterior Bankart repair using suture anchors.

BACKGROUND Arthroscopic repair of anterior Bankart lesions is typically done with single-loaded suture anchors tied with simple stitch configuration. HYPOTHESIS The knotless suture anchor will have similar biomechanical properties compared with two types of conventional suture anchors. STUDY DESIGN Controlled laboratory study. METHODS Fresh-frozen shoulders were dissected and an anteroinf...

BIOMECHANICAL ANALYSIS OF SUTURE ANCHORS AND SUTURE MATERIALS IN A CANINE FEMUR MODEL By JAMES

Knotless single-row rotator cuff repair: a comparative biomechanical study of 2 knotless suture anchors.

The purpose of this study was to compare the gap formation during cyclic loading, maximum repair strength, and failure mode of single-row full-thickness supraspinatus repairs performed using 2 knotless suture anchors with differing internal suture-retention mechanisms in a human cadaver model. Nine matched pairs of cadaver shoulders were used. Full-thickness tears were induced by detaching the ...

Biomechanical analysis of differing pedicle screw insertion angles.

BACKGROUND Pedicle screw fixation to stabilize lumbar spinal fusion has become the gold standard for posterior stabilization. A significant percentage of surgical candidates are classified as obese or morbidly obese. For these patients, the depth of the incisions and soft tissue makes it extremely difficult to insert pedicle screws along the pedicle axis. As such, the pedicle screws can only be...

Hypersensitivity to Suture Anchors

Hypersensitivity to suture anchor is extremely rare. Herein, we present a case in which hypersensitivity to suture anchor was strongly suspected. The right rotator cuff of a 50-year-old woman was repaired with a metal suture anchor. Three weeks after the surgery, she developed erythema around her face, trunk, and hands, accompanied by itching. Infection was unlikely because no abnormalities wer...
